DRYING FORMER AND SOCKET MEMBER THEREFOR.

Application filed. June 10, 1922.

To all via/10m 'it may concern Be it known that I, CHARLES HnnnnirrVan., a citizen of the United States of America. residing atGlove'rsville, in the county of Fulton and State of New York, haveinvented certain new and useful mproven'ients in Drying Formers andSocket Members Therefor.y of which the following is a. specification.

This invention relates to certain new and useful improvements in dryingformers and `socket members therefor and has particular reference to thegeneral improvement of steam drying forms of the type generally employedfor the drying and forming or finishing of gloves.

The principal object of the invention is to provide a steam drying formincluding a socket and a drying board carried thereby, cooperativelyconstructed for returning the water of condensation, which takes placein the board and socket, to the boiler or source of supply through themain steam pipe without additional piping.

`In the specific applica-tion of the invention to glove finishing forms,the device embodies a socket to which is attached a handlikefform whichis hollow and shaped like a persons hand with lingers but no thumb. Thesteam enters the hand and then passes up to the fingers through thesocket, and

- as it condenses the water formed thereby returns down the hand to thesocket thence back tc the boiler through the main steam supply pipe.

In so far as I am aware, sockets of this kind have all heretofore beenconstructed so that the steam, when it condensed, would form water inthe hand and fingers, thus causing the latter to become cool. A certainamount of heat is necessary to lay off leather gloves. Heretofore, whenthe hand `became cold by reason of condensation of steain forming in thehand, it was necessaryl to stop operating and draw off the water andthen again introduce live steam into the hand. The present inventionprovides a socket and drying board which are cooperatively constructedto permit the live steam to continue to flow through and into the hand,and as the steam condenses to allow the water formed thereby to flowdown the hand through the socket and then back to the main steam supplypipe to the boiler.

Another object of the invention is to pro- Seral No. 567,394.

vide asocket for steam drying forms embodying a control arrangement forsimultaneously introducing steam into'the form and permitting escapeofthe same to the atmosphere for removing air from the interior of theform, which means is further operable at will to close the atmosphericvent and simultaneously maintain the steam supply to the` form and opencommunication between the steam supply and the interior'of the form forthe return of condensation to the source of steam supplythrough the mainsteam supply pipe.

iVith the above general and specific objects in view, the inventionconsists in the novel form, combination, and arrangement of partshereinafter more fullyl described, shown in the accompanying drawingsand claimed.

In the drawings forming a part of this application and in which likedesignating characters refer t corresponding parts throughout theseveral views:

Fig. 6 is a side elevational view of the branch steam pipe supportingplug, and

Fig. 7 is a top plan view of thedevice shown in Fig. 6.

Referring morel in detail to the several views, the present inventionembodies a socket 5 having a control valve 6 and supporting a dryingform 7 which is herein illustrated in the form ordinarily employed forthe shaping of leather gloves and which embodies the usual palm portionwith four linger members 7', the socket 5 and the right position, andthis socket embodies a threaded lower end portion 8 adapted to besuitably connected to a. steam supply pipe, not shown. The upper end ofthe socket member 5 is enlarged and internally threaded as at 9 and isprovided with a smooth restricted bore just below this threaded portionas 10 for snug slidable reception of the stem 11 of the form member 7 apacking gland or bushingl 12 being externally threaded and screwed intothe threaded portion 9 with a packing 13 interposed between the inner orlower end of the bushing 12 and the shoulder 14 of the socket member 5so that a steam-tight joint is had between the stem 11 and the Socketmember when the bushing 12 is threaded into said socket member. It willbe understood the loosening of the bushing 12 will allow ready removalof the form 7 by reason of the stem 11 slidably fitting in said bushingalso, and in this way the forms may be expeditiously removed for theinsertion of different kinds of forms whenever found desirable.

A plug` 15 is suitably secured in the lower end of thevstem 11 and has areduced upper endportion 16 which is provided with a series of openings17 in which branch steam pipes 18 are suitably secured, one pipe 18being provided for and extending upwardly into each of the lingermembers 7, and the lower ends of said steam pipes 18 are allcommunicating with a relativly large axialboss provided in the remainingportion of the plug 15. The socket member 5 is provided, near thethreaded end 8, with apartition 19 having a threaded bore centrallythereof into which is screwed a relatively small steam conducting tube2O whose upper end removably lits the large bore of the plug 15..lournaled transversely of the partition 19 is the tapered rotary plugvalve member 6 having an operating handle 22 and provided with .a`plurality of ports 23` 24, and 25` the 'ports 24 and 23 being parallelwith each other and the ports 25 being at an angle to said ports 23 and24 for a purpose which will presently become apparent.

The inner end of the tube 2O communi- Cates with a segmental-shapedchamber 26 provided in the partition 19, which chamber extends from theinner end of the tube 20 laterally toward one side of the socket memberand this chamber 26 is in alinement with the port 23 of the valve member6, which port also communicates with the bore of the threaded portion 8.The partition 19 is also provided with a port 27 adapted to be alinedwith the port 24 of the valve member 6 and the port 28 adapted to bealined with the port 25 of said valve member 6, the port 28 beingextended laterally below the valve member 6 as at 29 for communicationwith the atmosphere or with a suitable vent valve of an'automatic type.The handle 22 may be provided with an inwardly projecting pin 30 and thebody of the socket member 5 at this point may have a flat surface ofenlarged form provided with an external arcuate groove 31 in which saidpin rides for limiting the turning movement of the valve member 6, thehandle being shown in Fig. 1 in a position wherein the ports 23 and 24are opened and the port 25 closed. The groove 31 is provided lwith agraduation or mark 32 for indicating the proper position of the handle22 when the port 25 is open, and the port 23 communicates with the tube2O by reason of the provision of chamber 26, while the port 24 isclosed. W'hen the handle is at the opposite end of the groove 31 orextends parallel with the longitudinal axis of the socket 5 the ports23, 24 and 25 will all be closed. In order to provide communicationbetween the interior of the .form 7 and the ports 27 and 28, the plug 15is provided with a plurality of longitudinally extending peripheralgrooves 33 which will allow the escape of air from the form 7 to theatmosphere when the port 23 is Vopened together with the port 25 whilethel port 24 is closed, or to allow the return of condensation form theinterior of the form 7 to the inlet end of the socket 5 when ports 23and 24 are opened and port 25 is closed.

In operation, the drying form 7 isoperatively connected to the socket 5,and the article to be Vdried is placed uponthe form 7. The valve handle22 is then turned to register' pin 30 with the graduation 32, vat whichtime the steam will readily flow from the supply pipe through the port23 into chamber 26 and thence into tube 20 and tubes 18. The port 24will be out of alinement with the port 27 or. in other words, port 24will be closed while port 25 will be open. The steam will escape throughthe upper end of `the tubes 18 and force the air which may be trappedwithin the integ rior of the form 7 downwardly through the `grooves andport 28 to the atmosphere. AS soon as steam begins to flow through theport 28 to the atmosphere the handle is turned to the full line positionof Fig. 1 so as to close the port 25 and open the' port 24 while stillmaintaining theport 23 but moving said port 23 to a position wherein thesame is longitudinally alined with ythe tube 2O as seen in Fig. 3. Theform 7 is then quickly heated and as the steam co-ndenses within theform 7 it will pass downwardly along theinner surfaces of; the form 7and through the groove 33 to' the port 27 from whence it may passthrough the port 24 and return through the main steam supply pipe to thesource of steam-supply for again being converted into steam. The conlOOopposite to the direction or' movement of the steam and the tact thatseparate return piping for the water of condensatio-n has been foundentirely unnecessary as long as separate paths for the flow of the steamand condensation is provided in the socket and Jform forinitially'estab-lishing a well dened circuit or passage for the steamand condensation. s
